Problem

The reference documentation for the FontManager class says that there is a singleton:

This module provides a single FontManager instance that can be shared across backends and platforms.

However, it doesn't mention that this singleton is named fontManager.

Suggested improvement

• The docstring should clarify that the singleton is named fontManager, rather than implying that the FontManager class is a singleton:

  This module provides a single `FontManager` instance, `fontManager`, that is shared across backends and platforms.

• The fontManager instance should be documented as a global variable:

  .. data:: fontManager
  
      The singleton instance of :class:`FontManager`
